Data analysis specialist Palantir has filed for a stock listing, the company said in a statement on Monday. The Californian company, which sells software used by governments and large companies worldwide, is looking to go public later this year, Bloomberg reported. It could be one of the biggest IPOs since Uber, with the secretive Palantir previously valued at $20 billion in 2015 -- although it wasn't clear what valuation the company would seek in going public. Palantir said it had "confidentially submitted a draft registration statement... with the U.S. Securities and Exchange Commission relating to the proposed public listing of its Class A common stock. "The public listing is expected to take place after the SEC completes its review process, subject to market and other conditions." juj/je/fox
